Mosin Tech

Hey guys I have just been in the shop at work and noticed a few small hole tips laying around for a mig welder...the wire had stuck in them and they were no longer serviceable...I looked at them and had an idea, I wonder if I can fire those as bullets since they are solid copper...I miced them right at .311 and I resized them .310 for my m39...long story short they are about 1.4" long and weight right at 190 gr...I shot them today and they cut nice round holes...I loaded the threaded side out like a hollow point...so if you have any access to these it would make a good hog thumper and give deep penetration...
